CCNE WIEDER. VVI'I-Iy THREAD-SEVERING ATTACHMNT.

Application filed October `29, 1923. Serial No. 671,314.

To all whom t may concern.'

Be it lrnoWn that ELMER VAN DUsnN, a citizen of the United States, andresident of Stratford, in the county of Fairfield and State ofConnecticut, has invented certain neW and useful Improvements in ConeWinders With rl"hread-Severing `Attachments, of Which the following is aspecilication.

This invention relates to a cone Winder, and has more particularreference to a machine for Winding a thread of yarn, as from a cop orjack bobbin to a Winder bobbin, equipped With an attachment for severingthe thread should the same become accidentally removed from its guide.

Ordinarily, yarns for knitting yarrive at the knitters on cops or jackbobbins, and to facilitate knitting are Wound off on a much largerbobbin, called a Winder bobbin. Great care must be taken to have theyarn in the best possible condition on these Winder bobbins, as thisWinding is the last handling of the yarn before it goes into the needleson the knitting machine. With certain types of cone Winders noW in use,the

` thread of yarn as it is being Wound off of a cop or jack bobbin onto aWinder bobbin frequently becomes displaced from its guide, usually aporcelain guide movable With the building rail, to Wind irregularly,alternately upon said Winder bobbin at locations beloW those Whichshould receive the thread, and beneath the same upon the bobbin spindle.Naturally, such Winding of the thread of yarn renders the yarn upon theWinder bobbin unt for presentation to a knitting machine. The Whole of,or a large portion of, the strand or thread must be removed and properlyreWound. The present invention purposes to preclude the possibility ofimproper Winding of the thread of yarn by reason of the thread leavingits guide.

lt is, therefore, an object of the invention to equip a machine of thecharacter mentioned With means for severing a thread of yarn being Woundas soon as said thread has become removed from its guide, in order thatthere can be no further Winding of the thread upon a bobbin or the likeuntil an operator has tied together the severed ends of thread andreplaced the same in its guide.

It is a further object of the invention tov equip cone Winders havingthread guides movable With their building rails With thread severingattachments adapted to cause threads of yarn being Wound to be.

cut or broken should said threads become removed from their guides tothus preclude further Winding of yarn until the severed ends of threadare joined and y the thread is reinserted in its guide. l

Numeral 14 represents spaced apart strips of boarding extendinglongitudinally across the top of the machine frame, and l representssimilar strips arranged beneath the strips 114:, in which stripsvertical bobbin spindles 16, extending upwardly beyond the strips 14,are mounted. 17 is a receiving shaft beneath the 'strips la and abovethe strips l5, and preferably halt-way between the'sides of the machine,arranged longitudinally of the trame and mounted inthe end members andll to extend beyond said end members. 18 denotes power receiving'pulleys upon the receiving shaft and beyond Vthe end member l0, and 19denotes band pulleys for driving the spindles le', each of said"spindles having a pulley 2O receiving a'banding 2l traveling over aband pulley 19. Each band pulley, as disclosed, has a double groove, todrive a spindle l@ oireither'side of the machine. 22 are winder bobbinsremovablysituated upon the upper ends of the spindles 16, above the'strips 14., to be individually `stopped when this is desirable, andeach winder bobbin can have its own stop motion (not shown) to ceasewinding when illed with thread of yarn. rt the'end of the receivingshaft i7 opposite the power receiving pulleys and beyond the end memberll, is a receivingl pulley 23, 'for transmittingl power `to the buildingmotion inside the lower part of the machine as in Figs. land 2. A belt2a passing-over the pulley 23 alsozpasses over a pulley kon a `lshalt 26outside the end ame and Amounted in the end member il A pinion 2i' on 'iin any suitable manner. saidshaft 26 meshes with a gear 28 on ajacks'haft 29, also outside the end trame il. double pinion gear 30 onsaid jackshait 29 and within the trame meshes with a double gear 3l on ashalt 52 suitably mounted in the trame so that the teeth of one pair ofgears are just half the distance otone tooth ahead ot the otherpair-this to lessen backlash.

Upon the shatt 32 is a heart cam 33 adapted to impart to the buildingrail 34C a slow rising movement, making a close wind on the bobbin, anda quick falling -movement which lays the yarn across the close wind andbinds it to the winder bobbin. The lift ing rail, see Figs. l and 2, isconnected with the heart cam -in the following manner. By action of thecam, a lever 35 on a rockshait 36 parallel to the shaft 32, is made totransmit its motion by means of a chain belt 37 attached to said lever35 and running over an idler wheel', to connect said lever with a secondlever 39 on a rocksha'tt 40 at right-angles with the shaft 32. @n thisrockshatt l0 other levers, denoted al, are connected by un'right rods tothe` building rail to give to said rail a rise and tall preferablycorresponding to thev height ot the cone-shaped portion ot' the Winderbob bin. Un another lever e3 oi the rocksha'i'l, l0 is a ball weight Llto equalize the motion, balance'the weight of the building rail, torelieve the heart cam oi" excessive weight when lifting the rail. Thelirst upright rods to the building rail are,'as shown, near one end ofthe machine. `he rookshatt 40 with lifting rods and ball counter weightcan consequently be duplicated to manipulate all other upright rods 4:2,the rock'shatts el() having levers 4-connected by links 46. The uprightrods l2 are desirably notconnected with the levers 4l, but each has abroad heel 47 to ride easily on a small roller wheel (not shown) inthe'ends ot' the levers.

The building rail Sil may be secured to the upright rods l2 in anysuitable manner, as denoted generally at a8, preferably to be separatelyadjustable on each ot said upright rods.

The cops are shown placed in their proper positions just under thecotton friction or cleaner rails 50 mounted at leither Lsine ot theframe adjacent the `upper side members l2 and extending longitudinallyofthe machine. llhe yarn isadapted to pass from a cop through the insidecurl ot a double quirl guide wire (not shown),'then through an outercurl 5l., over a felt 52 and throng-h a Vporcelain pot'eye guide52-3,`said curb telt and eye guide all being upon thecleaner rail 50,and then to a Iporcelain 'guide'llattached to a v-triction cup on ascrew f'spindle 5G extending upward trom the building rail, to be thrownaround a cloth covered part (not shown) of the winde'rlbobbin'to whichitclings and therebygets its start.

The friction cups 55 may be associated with the screw spindles 56 in anyapproved manne-r, to control the diameter of the bobbin. As shown, whenthe yarn builds the bobbin to the required diameter at its base the yarnrubs the cup to move it around and up on the screw spindle, as is wellunderstood in the present art.

The porcelain guides fill are attached to the friction cups as by meansof wires 57, to move upwardly or downwardly with said cups, but saidguides 54 are liXed against lun lll)

i2 spindles.

As long as the threads of yarn pass over the porcelain guides `54movable with the cups, during each successive reciprocation of thebuilding rail said yarn does not Wind on the Winder bobbins as far downas it did on the preceding reciprocation. That is, a cup and the yarnWith it move up gradually until the bobbin is full to the top of thespindle, preferably leaving the top l in the shape of a cone just as ithas built it all the way up.

If desired, the building rail can be given, and usually is given,endwise reciprocation during its vertical reciprocation in order thatthe yarn may not run in one crease on the felt 52 upon the cleaner rail50.

In the machine well known and briefly described, the thread of yarn asit is being wound off of a cop onto a Winder' bobbin frequently becomesdisplaced from its porcelain guide 54 to thereafter travel over thebuilding rail 34 so that the thread is wound alternately upon the Winderbobbin at locations below those intended to receive the thread, andbeneath said Winder bobbin, upon its spindle, thus ruining the Woundbobbin for its intended purpose. To obviate this difficulty, I providethread severing attachments adapted to extend the full length of themachine, from end to end thereof, and I preferably secure saidattachments to the inner faces of the building rails 34, as by means ofthe screws 62.

As very clearly shown, each severingl ati" tachment includes preferablysaw shaped Iteeth 63 which protrude upwardly beyond the building railand desirably outwardly away from the Winder bobbins. Clearly, should athread of yarn become removed from a porcelain guide 54 during thewinding operation, as shown by the dotted line in Fig. 4, it willimmediately be drawn against a tooth 63 of the severing attachment whichwill act as a guide to turn the thread into one of the slots between theteeth, these slots being tapered to pinch the thread and thus cut orbreak it as the Winder bobbin rotates to stretch the thread tight.Naturally, there can be no further winding of the thread until thesevered ends are connected. To connect the ends the operator releasesthe Winder bobbin from its spindle, and after the tie is made, reinsertsthe thread of yarn into its guide 54 and allows the bobbin to again turnwith its spindle.

It is to be understood that the teeth 63 of the severing attachment neednot be of the exact construction shown. For example, certain teeth canproject toward the right as disclosed in Fig. 5, While others projecttoWard the left, ydependingA upon whether the bobbin is being wound fromleft to right or vice versa, theidea being to provide severing teethbest adapted to their purposes.

It is to be further understood that while I have shown the inventionapplied to a Payne cone Winder, it is applicable to other styles andtypes of winding machines. Furthermore, the severing attachments neednot be carried upon the building rails as illustrated and described, butmay be otherwise associated with the particular machine disclosed orwith machines of different types in connection with which saidattachments would be useful to be movable with, or not movable with',the thread guides, as preferred.
